Meaning of Survey
What is Survey:
As a survey it is called a data collection technique for social research. The word comes from French enquête, which means "research".
As such, a survey is made up of a series of questions that are directed to a representative portion of a population, and its purpose is to find out states of opinion, attitudes or behaviors of people regarding specific issues.
The survey, in this sense, is prepared by a researcher who determines which are the most pertinent methods to grant it rigor and reliability, so that the data obtained are representative of the studied population. The results, on the other hand, are extracted following mathematical procedures of statistical measurement.
See also Statistics.
Depending on the universe studied, the proportion of the representative sample of a population will be defined. Although in the case of very small populations, one hundred percent of the individuals may be surveyed. Thus, a survey will be designated as partial when it focuses on a sample of the total population, and it will be called exhaustive when it covers all the statistical units that make up the universe studied. The population, on the other hand, could be made up of people, companies or institutions.
See also Sample.
The survey application process is generally carried out by an interviewer, who is in charge of data collection. Surveys can be face-to-face, by phone, by mail, or online. They are commonly applied for market research and opinion polls of a political nature (elections, approval, popularity, etc.).
See also Data.
The objective of the surveys is, mainly, to gather a large amount of quantitative information on specific topics that affect society, as well as to know the opinions, attitudes, values, beliefs or motives that characterize the citizens of a given country. or region. In this sense, according to authors such as Manuel García Ferrado, "all social phenomena can be studied according to surveys."
As a survey, it can also be called the printed paper where the list of questions that make up the questionnaire is found.
See also Questionnaire.
Survey and interview
The interview is a social research instrument to apply surveys where you have direct access to the individuals who are part of the studied population.
In this sense, the interviewer can obtain subjective data from the respondent and information about their environment, collecting not only their responses, but also relevant aspects that arise during the interview.
Some advantages of the interview survey is that it is more direct, personal, specific and immediate in terms of data collection.
